This fellow’s tooth was wacked when he was young. Wear a mouthguard when playing sport please guys! The existing filling was leaking and broken and the tooth had gone dark. The blood in teeth stains when the nerve dies, and also the medicaments used in root fillings may stain the tooth. Ideally the tooth would be bleached as a conservative option. The filling was failing so the next best option would be a crown. Unfortunately this tooth is on its way out – it is so hollowed an weak it wont hold a crown but we had to do something because the current filling is failing.
We built him a new tooth using a carbon fibre post into the root, and bonding dental composite resin over the top. It is much cheaper than a crown, and if the tooth fails he is looking at a gap, denture, or implant. Hopefully we have delayed these options for some time to come and given back a smile.

This patient was a pleasure to treat. As you can see there was some crowding issues with the front 2 teeth and all the teeth were quite dark. We bleached the teeth using at home tray whitening for a couple of weeks, and match full porcelain Empress crowns cemented onto the front 2 teeth. The full porcelain allows the light through them just like natural teeth so the result is very aesthetic. Traditional porcelain fused to metal crowns (PFM’s) tend to result in a more opaque ‘non-vital’ appearance.

Well, I have been a bit slack in writing new info. It takes time to get interesting photos and new ideas, although I see them every single day at work. I guess this post is to ask people for their dental problems, queries. I am here for free consultation – obviously I can’t look in your mouth, but I can give advice generally about dental questions you have. It will give me more info on what are the dental concerns people have that I can help with via the net. I mostly get wisdom tooth questions but thought this post might stimulate some others.
I’ll have a post coming soon on bleaching and full porcelain crowns for crowded front teeth based on an interesting patient I have just had the opportunity to help. Come and check it out in the next day or so.

There are many ways to whiten teeth. This is what I have been investigating for a long time. The over the counter options are usually limited due to the strength of the bleach. Most dentist prescribed whiteners are 10 -20% Carbamide Peroxide, while chemist bought bleaches are usually 1-2%. Whitening toothpastes are not of sufficient strength and are only in the mouth for a minute or two so there is a negligable effect with these.
The key is to get a strong enough bleach on the tooth for a long enough time. We have started using a sopisticated system to make the best fitting home bleach trays EVER! I imported the technique from The States in December and now have bleaching trays that fit beautifully. This means the gel stays on the teeth, and saliva can’t dilute it. The results have been amazing.
The icing on the cake is to try deep bleaching – a specific technique using in surgery bleaching combined with at home bleaching. I have just started a few cases and have been really impressed to finally get some predictable results.
